I am Professor Emeritus of Tomographic Imaging at The University of Edinburgh, where I was Head of the School of Engineering (2013-2018). I graduated in Physics (1976) and PhD in High-Energy Particle Physics (1980) at the University of Glasgow, and then carried out 6 years of post-doctoral research at DESY (Hamburg) and CERN (Geneva). In 10 years at the Royal Dutch/Shell Group, I  was founding Group Leader of Shell’s specialist Engine Measurements group, and won the Colwell Merit Award of the Society of Automotive Engineers (1995).

I was Professor of Industrial Tomography at UMIST/University of Manchester (1996-2013), Head of Electrical & Electronic Engineering (1999-2002) and Associate Dean (Research) in the Faculty of Engineering and Physical Sciences (2010-2013). I chaired the UK Professors & Heads of Electrical Engineering (2003-2005), the IET Scholarships Committee (2006-2009), and the EPSRC Strategic Advisory Team on Capital & Equipment (2014-2017). I have taught measurement and instrumentation at all undergraduate and postgraduate levels.

In both Manchester and Edinburgh, my research groups have focused on Agile Tomography, with applications mainly in engineering processes. I pioneered the technique of Chemical Species Tomography, using opto-electronic systems to provide in situ specific chemical imaging capability in various combustion systems, with funding from EPSRC in the UK and from the European Union. This work has been carried out in partnership with several companies, such as Shell, Innospec, Rolls-Royce and Revolve Technologies, and was awarded the Maurice Beck Prize of the World Congress in Industrial Process Tomography (2007).  I developed electrical impedance tomography for medical applications, funded by Wellcome Trust and EPSRC. I am author/co-author of more than 110 articles in peer-reviewed journals. Having been elected a Fellow of the Royal Academy of Engineering in 2009 and the Royal Society of Edinburgh in 2015, I was appointed Visiting Professor (2014-date) in the School of Instrumentation and Opto-electronics, Beihang University, Beijing, and I was appopinted Honorary Professor of Beihang University in 2018.
